Population Dynamics
22
Habitat: an organisms home is known as their …
crude density: population density measure by the number of same species
quadrat: sampling frame for estimating population
demography: study of the growth rate, age structure and characteristics of a population
natality: birth rate of a population
emigration: movement out of the population
cohort: individuals of similar ages
fecundity: how likely a species is to reproduce in a lifetime
predation: interaction between predators and preys
limiting factor: density-dependant factor and density-in-dependant factor are considered
coevolution: species evolve due to the evolution of other species
herbivory: interaction between herbivores and their food
mutualism: both populations benefit
paratism: one species benefits, the other is harmed
commensalism: one species is affected and the other is not
mimicry: defence where one species evolves an appearance that looks like another species
pathogen: disease causing agent (fungus)
epidemic: spread of disease which is not local
malnutrition: when body lacks nutrients
salinization: addition of salt to soil
aquaculture: raising fish and shellfish for crops
biocapacity: ecosystems ability to produce materials and absorb waste materials
